It's difficult to make the functional devices of Metal-organic frameworks (MOFs) due to its inherent flaws such as fragile, thermolabile, etc. However, the porous metal materials has an advantage in a strong resistance to stress and high ductility. The project intends to design and developed a high performance composite porous material and its devices through the proper adjustment both microscopic structure of MOFs and porous metal and make them effective composite. Mainly study the following two topics based MOFs in gas adsorption, separation, and catalytic application-oriented through synthesis the composite material of excellent MOFs with various types of porous metal. ① Explore the synthesis method of such composite materials and composite rules. Strive to obtain a simple and efficient synthetic method of the composite material. ② Study the adsorption and separation performance of the composite porous material to the gas such as CO, NO, CO2, N2, CH4 and H2, and its heterogeneous catalytic performance. Strive to screening several high performance composite materials to achieve functional devices, and to study its application in the treatment of industrial waste gas and organic synthesis. Through this project, new ideas, new theory and new technology in the preparation of such composite materials will be obtained. It is expected to achieve the practical value of such composite in adsorption, separation and catalysis.
